IMPROVEMENT lN WASTE AND OVERFLOW PIPES 0F WASH-BOWLS S INKS, 85c.

Specification forming part of Letters Patent No. 179,08 3, dated June20,1876; application filed April 12, 1876.

To all whom it may concern:

Be it known that I, GEORGE E. WARING, Jr., of the city and county ofNewport, in the State of Rhode Island, have invented a new and usefulImprovement in Waste and Overflow Pipes of Wash-Bowls, Sinks, and otherarticles of a similar nature, which improvement is fully set forth inthe following specification, reference being had to the accompanyingdrawing, in which- Figure 1. represents a horizontal section of awash-bowl provided with my improvement. Fig. 2 is a vertical centralsection of the same.

Similar letters indicate corresponding parts.

This invention consists in the combination of a stop-cock, faucet, orother stopper with the overflow-pipe of a wash-bowl, bath-tub, sink,laundry-tray, urinal, or other article of a similar nature, and with thestop-cock or faucet of the supply-pipe, so that when the supply-pipe isopened and the overflow-pipe may be required, the stop-cock, faucet, orstopper of the overflow-pipe is also opened; but when the supply-pipe isclosed, and consequently the overflow-pipe not required, the stop-cock,faucet, or stopper of the latter is closed, and the escape ofsewer-gases into the house is prevented. a

In the example represented by the drawing, the letter A designates awash-bowl, which is provided with two supply-cocks, B 0, (one for hotand the other for cold water,) and with an overflow, D, which connectsby means of a pipe, E, with the waste-pipe F. Said pipe E is providedwith two stop-valves, B O, which are connected to the supply-cocks B U,respectively, in such a manner that the same open and close as thesupply-cocks are opened or closed--that is to say, when the supplycock Bis opened, the stop-valve B opens, and vice versa, and the same with thesupplycock 0 and stop-valve G.

' Whenever one of the supply-cocks B or G is opened, and, consequently,whenever the overflow may be required, the corresponding stop-valve B orU in the pipe E is also opened; but as long as both supply-cocks B and(l are closed, the comm'unicationbetween the overflow D and thewaste-pipe remains also closed, and the escape of sewer-gases throughthe overflow is effectually prevented. It is obvious that the stop-cocksB B and G C may be arranged in various ways, so

that by opening one of the supply-cocks the corresponding stop-cock ofthe overflow-pipe will also be opened, and I do not wish to continemyself to any particular form or construction of stop-cocks.

The waste-pipe F communicates with the waste-opening G in the bottom ofthe bowl A. In this wasteopening is secured a valvechamber, H, whichcontains a valve, I, that is pressed up against its seat by a spring, J,its

stem being held in position by suitable guides K L.

When the valve I is closed, there are no depressions, creases, orirregularities at the bottom of the bowl for the accumulation of filth,and by depressing the valve 1 against the spring J the bowl can bereadily emptied, and when the bowl is empty the valve I closes andprevents the escape of sewer-gases into the house.

It is not necessary, however, in applying this part of my invention, touse the spiral spring arranged as stated, nor to depend upon a manualdepression from above to open the waste. The valve I may, for instance,be supported by a lever, one end of which communicates with a stemrising through the slab or above the side of the vessel, arrangedinpipe.

It is obvious that my invention is applicable to bath-tubs, sinks,laundry-trays, urinals, or all other articles of a similar nature. it

What I claim as new, and desire to secure by Letters Patent, is-

The combination of a stop-cock, faucet, or other stopper with theoverflow -pipe of a Wash-bowl or other ztrticieoi' a similar nature, andwith the stop-cock or faucet of t the supply-pipe, said stop-cocks heiugconnected, so i that they open audelose simultaneously, substantially asset forth..
